Poopy Head

Poopy head is a sexual act in which two people have anal sex but the person receiving the anal must take a shit and not wipe before the anal and the person giving the anal must not wash their penis after the anal, it is also an insult for someone who does that

Girl 2: I think that guy likes poopy head
Girl 1: eww, I'm gonna go wash my mouth
